The -present invention relates to an improvement in wind-motors of the type wherein the vane wheel is equipped with rigid swivelling vanes which, on being acted uponby W a regulating device by means .of a sliding member mounted upon theiwheel shaft, s0 turn as vto escape the effect of too violenta wind, through modification of their angular' position with respectto the general planeof g *P110 the Wheel.

In one of the recently known types of these machines, the rigid vanes carry, upon Athe extension of their transverse edge nearest the Wheel centre, .5a. swivel which is attached, by

- V means of a flexible connection, tothe external hoopiwhich is the.. actual rim of afslidng member mounted upon the shaft and keyed uponit, whereby they jointly rotate, in such a manner that, whenever the regulating device acts. upon the ,sliding member, thelatter will, in its turn, and by means of tlie flexible connections, cause the vanes to alter their, an-

gular position with yrespect to the 'general plane of the wheel, to 4be afterwards caused A p25 toresume'their initial position under cooperai tion of return springs, as soon as the traction eort has ceased, l y l, A

According to thepriinary principle ruling thev function of aero-motors of this descripv430 tion,`the vane should get open so as t'o stand vperpendicular to the plane of the vane wheel, failing which it'V cannot vbe possible to have v the machine stopped neither to obtain a'regu- `lar motion, it being even impossible to sufliciently protect the aero-motor against the destructive action of too violentwinds, especially of wind gusts which are so detrimental to its existence.'

Now, 'assuming the flexible connection to 40 have been fastened tov such a point of the sliding member rim as would, with respect to the .i general plane of the aero-motive wheel, lie in front of the point where the connection is attached to the pivot of the lower arm of 45., the vane, the latter though acted `upon by the pull from the sliding member, can only be girned in an angle obviously smaller than On the other hand, assuming the point whereat the cable is attached to the rim of the slidingmember tobe, for instance, shifted more to the right, so that the vane, acted upon by its connection under cooperation of the pull from the sliding member, will tend to open as much as 90, not only will such an arrangement be difficult to carry out in the case of said connections being flexible owing to the presence-of the propping spokes of the wheel), the system will be, besides, liable to a great drawback in that, when the Y sliding member mounted upon the wheel shaft acts uponthe vanes by means of the connections, these will, in'turn, and owing vto their being inclined to the directionfof her, the direction of its displacement will be parallel yto that of theL sliding member. so that this connection will exert upon the sliding member a. pull in a direction parallel to that of the vane wheel shaft. As a result of this arrangement, any lateral effort ererted by the connections upon the peripheral rim of the sliding member, is avoided, as

is likewise avoided any abnormal friction thatv would be exerted upon the cotter.

To facilitate comprehension of the principle and form of embodiment of this invention, thefollowing description refers to the accompanying drawings, wherein:
